No diagnostic performed while typing.

Coc-java isn’t linting while I type. The only time it lints is when I save the file. Trying since many days to perform : Debug Language Server but failing miserably. Output of :CocList services looks bit strange : Nevertheless, I added "Language Support for Java.trace.server" : "verbose" to my coc-settings,json which makes it look like

{
    "coc.preferences.extensionUpdateCheck" : "never",
    "diagnostic.refreshOnInsertMode": true,
    "diagnostic.checkCurrentLine": true,
    "diagnostic.displayByAle": false,
    "python.linting.enabled" : true,
    "python.linting.pylintArgs" : ["--load-plugins", "pylint-flask", "pylint-flask-sqlalchemy", "pylint-sqlalchemy"],
    "suggest.noselect": false,
    "suggest.autoTrigger": "always",
    "suggest.triggerAfterInsertEnter": true,
    "Language Support for Java.trace.server" : "verbose"
}

which is certainly wrong. I changed the last line to "java.trace.server" : "verbose". Writing :CocCommand workspace.showOutput shows a huge log. click here to view I uploaded it and viewed on Microsoft LSP Inspector but I don’t know what I should look for. Any help to further progress the debugging would be divine. My goal is to make coc-java lint my java files (and display the diagnostic) while I type. Other Information : :CocInfo shows

Could be problem of your language server, checkout https://github.com/neoclide/coc.nvim/wiki/Debug-language-server#using-output-channel

Diagnostics only refreshed on insert leave by default, use "diagnostic.refreshOnInsertMode": true in coc-settings.json

Search textDocument/publishDiagnostics, seems your server working as expected, but I don’t know why you didn’t get diagnostics.
